Which of the following methods is categorized as internal marketing for a golf shop?

Internal marketing focuses on promoting the organization’s mission, values, and services to its employees and stakeholders, fostering a positive environment and encouraging staff engagement. When staff members actively participate in marketing initiatives, they become valuable ambassadors for the golf shop, conveying enthusiasm and knowledge about the services and products offered. This method not only helps in building a strong internal culture but also enhances the customer experience, as well-informed employees can provide better service and promote the shop's offerings effectively.

In contrast, print advertising, customer referral programs, and online promotional offers are external marketing tactics aimed primarily at reaching customers outside the organization. These methods do not directly involve or leverage the inherent capabilities of the staff within the golf shop, which is the core of internal marketing.
